If you are sending emails to business clients support for Outlook 2000-2003 & Outlook 2007 is still essential. I'm afraid you need to code them like it's 1999. MailChimp have a guide on how to do it right: http://mailchimp.com/resources/guides/email-jitsu/

Fortunately a <table> is (and always has been) responsive.

For non-business clients (who would be unlikely to use Outlook at all) these look great.

100% agree. Outlook doesn't support responsive CSS... but doesn't it support conditional comments? I think Zurb might be missing an opportunity here.

Outlook is the IE6 of the email design world.

I'd actually say it's more like the IE5 for Mac of the email world.
